' GATE-HINGE.

SPECIFICATION formingpart of Letters Patent No. 235,500, dated December 14, 1880. Application filed December 27, 1879.

To all whom it may concern:

Be it known that I, WILLIAM H. BOND, of Greensborough, in the county of Henry and State of Indiana, have invented certain new and useful Improvements in Gate-Hinges; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making apart of this specification, and to the letters and figures of reference marked thereon. Figure 1 of the drawings is a representation of a perspective of my gate, and Fig. 2 is a view of the hinge.

Thenature of my invention relates to that class of gate-hinges in which the pintle of the gate portion of the hinge works in a slotted plate secured near the lower part of the post.

A hinge of such description has already been secured to me by Letters Patent, and hence in the present case I deem it only necessary to point out my improvement thereon.

I In the drawings, A designates a gate of any ordinary or desired construction. B represents the latch-post, and O the usual hingepost.

The upper hinge, D, consists of a pintle secured by a shank to the post and an eyebolt secured to the gate.

Thelower hinge comprises the pintle part E, which is secured to the gate, and a doublefianged or angle plate, F, which is formed with a curved slot, Gr, and secured to the post by means of screws or bolts passed through the flanges. This plate F is convexed at its upper surface, as herein shown, so that the curved slot will also have a convex conformation in the direction of its length. By reason of this peculiar shape it willbe seen that the highest portion of the plate which is adjacent to the slot forms a shoulder against which the shoulder upon the pintle will bear when the gate is either open or shut.

dle of the slot-that is, at a point intermediate of its ends-the shoulder of the pintle will be at the highest part of the slotted plate, and hence that the gate will be raised sufficiently to automatically disengage its latch H from the catch I. As the tread is further swung or vibrated so that the arm of the same which is being depressed comes into a horizontal position the connecting-rod will force the gate into such an angle that it will swing either open or shut, according to which one of the arms K is depressed.

The object of making the slot curved instead of straight is to form a bearing or shoulder between the ends of the slot, to prevent the pintle E from being slipped back to the end of the slot from which it has been drawn, which is done where theslot is straight by the weight of the gate after it has been raised from its latch and before it has swung one-half of the whole distance it has to travel to reach its other latch, and which slipping back will cause the gate to fall back to its first position should the tread be accidentally released, or released too soon. This defect is overcome by the use of the curved slot, as the highest point and the top of the curve are both between the ends of the slot, and the bearing or shoulder formed thereby will cause the weight of the gate to force the pintle toward that end of the slot to which it has been drawn.

What I claim, and desire to secure by Letters Patent, is-

1. In a gate-hinge, the herein-described angle-plate, formed with a curved slot through its portion F, and the pintle E, arranged to work therein, substantially as set forth.

2. The gate with pintle E, in combination with the curved plate F, with slot G, the tread G, and rod H, substantially as set forth.

In testimony that 1 claim the above I have hereunto subscribed my name in the presence of two witnesses.

WILLIAM HENRY BOND.
